last printed sheet at a'uniform distance from the sheet conveying mechanism.

The framing of the pressis open at one or both sides adjacent the delivery boards 19 and :20, so that thE pile of sheetsjaccumulated thereonv may be readily removed.

Preferably I provide with each sheet vboard vthe usual joggers 21 to secure the proper registration of the sheets as piled.

. means which may be rendered active or yinactive at the will of the operator, whereby the sheets may bedelivered to any one ofthe sheet boards `or other support and whereby when a-pile of sheets has accumulated upon any sheet `board ythe sheets may at thewill vof the operator be delivered past such filled boardor to any unfilled board, all without stopping or slowing the printing mechanism or interfering with the sheets being printed.

It is apparent that in this manner the ac cumulated sheets may be removed froml anyv pile while other sheets are being delivered to lanother sheetboard, and if but a pair of' such sheet boards be provided the sheets may be delivered first to one and then tothe other board until filled, each boardbeingemptied during the filling of the other.

next sheet upon another pile, so as'to allow more time for the ink to dry uponeach sheet before another sheet is'superimposed thereon. In this manner alternate sheets 'may be placed upon alternate piles orsuccessive sheets may be distributed upon any number of piles. If desired, however, I may cmplete one pile from consecutive sheets and then complete the next pile from consecutive sheets printed and delivered thereafter. Any suitable means may be employed to stop the sheets for the purpose indicated. Preferably I' providemeans adapted to be operated at the will of the operator.' Hereinv for the purpose I have indicated in Fig. 1 adjacent the forward end of each sheet bpard sheet stops 22-22pivoted upon the framing at'a suitable distance above the bridges-17 and provided -with handles 23 which may bel I contemplate the employment of suitable or someclassesjif work it may be advantageous to` arrange an automatically acting stop so that A a sheet may be placed on one pile and the thrown to' therightto bring the sheet stops. into engagement with limiting pins 24-,21 as indicated -in Fig'. 3.'. These stops are arranged in transverse series a't each delivery board. In Fig. 1, thwight vhand stpb-r-q set of stops 22 is not shown aslprovided with means to render it activeer-inactive, but v is apparent that it may be so provided,` as i 'for example'if another-delivery board be arranged in advance thereof or if for any reasozfitbedesired 4tplermit -the sheet to be discharged at the front of thepress.

'When' the stops 22 are in the\position shown in Fig. l, they are rendered active, but if swung to the right viewing said ligure they will be rendered inactive. While the stops may beof any suitable character, preferably I render them yielding, so that while they project below the. upper 'surface'of the' l bridges 17 they may7 yield and ride over the tops 'of the. bridges, should this be necessary. The steos are hereinshown as brush-like in suitable construction may be employed.

Thesheets are deposited singly and con.V

`character for this purpose', but any other secutivelv uponthe bridges17 as they pass Abeneath. the delivery cylinder and are car- Aried forward thereby and preferably beneath strin s or tapes'25 passingabout the delivery cy inder7 andl guiding rolls v26-26v mounted in the'framing, the said strings or tapesbeing driven at substantially the same speed as the bridges and serving to prevent vthe* front edges of the sheets from winding 0rcurling up and folding backupon themselves.

When' a sheet contatswith a stop orset of stops whi'ch is active,'the result is'to stop the sheet, the supporting bridge 17 passing from under the same and permitting board or pile of sheets, the several bridges being'suitably spacedv to permit such-depositing of the sheets. When the vsheets are not" l very thin and flexible, the stops engaging, the leading edges thereof are'suilicient to. stop-the sheets and to cause them to be piled upon the delivery boards, but for very thin orflexible sheets I preferably provide means for stopping the tail ends of the sheets or parts of the sheet to the rear of the leadingr edge thereof at substantially the same time ,that the front ends are stopped. The'pur- 'stops are then suiicient and effective to prevent anv forward' movement of any part of the sheets with the bridges 17.

105 the sheet to drop upon its proper delivery y rss 2T-427 may be adjusted latuitable means not shown and i be adjusted longitudinally of the press by any suitable means not shown `in order to position them properly with respent to the p icnlar work and so that they 'may contacu th uninked portions of the sheets. The stops 22 are made in the manner described to permit them to yield to the rolle-rs 27 ifV the latter have been laterally adjusted into alinement therewith.

In Fig. 4 l have represented a two revolution rotary printing press wherein the impression cylinder Q9 makes two revolutions, printing the sheet during one of said revolutions and delivering it forwardly during the second revolution. The usual grippers 30 release the front edge of the sheet as it is raised by the usual sheet lifter lingers 31 and the sheet stripped from the cylinder by the usual'stripper fingers 32. 'The sheet conveying mechanism may be and is here shovfn substantiall;Y similar to that illustrated in Fig. 1.

it is apparent that the mechanism herein illustrated may be used in connection withY any desi type oi printing press or other mechanism adapted to deliver sheets consecutively.

From the foregoing description it will be apparent that l amenabled by my invention to continuously operate a printing press at any desired speed so as to deliver sheets therefrom singly and. consecutively and .without interrupting in any manner or slowing down the feed of the press. I may shift or shunt the delivery of the sheets from one receptacle or delivery board to another. thus permitting` the filled receptacle or suitable pile to be removed from the press without stopping 0r slowing down the latter. the delivery'ofj sheets being shifted by the operator from one to another receptacle fvdenository as a sufficient pile' accumulates thereat. In this manner the output of the press is very substantially enhanced.
